Abstract: 123,123. Bilby, J. A., Close, W., and Palmer, P. G. Dec. 12, 1917. Rotary cylinder and like apparatus, internally illuminated.-Relates to rotatable drums bearing advertisements and adapted to be turned through a given angle by a distant switch. The invention comprises the actuation by the drum when operated of means near the switch to indicate to the operator that the drum has come to rest at the required position. The means is not shown in the drawings, but may comprise a series of electric lamps in, say, a battery circuit and illuminated in turn by a rotary switch operated by the drum. The drum-actuating apparatus consists of a motor 4, the circuit of which is made and broken by a contact 13 which touches one of a number of metal strips 11<b> arranged round a disk 11 of insulating material mounted to rotate with the drum. The strips 11<b> are each connected to a ring 10 on the drum axis, each ring being in contact with a tongue 9. Each tongue 9 and the contact 13 are in circuit with the motor 4 and with the distant operating switch, which consists of contacting fingers arranged in a circle and adapted to be separated by a rotatable arm. The drum thus rotates till the contact 13 comes against the strip 11<b> which is connected electrically to the fingers separated by the switch arm. As shown, the strips 11<b> and the contact 13 are formed with depressions so as mechanically to lock the drum, when it stops, in the exact position required.

Abstract: 184,451. Quinan, K. B. Aug. 6, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Coking processes.-Coal, shale, wood &c. is distilled in a retort R by the passage therethrough of hot gases which travel in a closed circuit comprising a fan F superheater S, retort R, and condenser C. Condensates are collected in a tank T and surplus gas escapes through valve V.

Abstract: 1, 084, 518. Automatic control. EDWIN DANKS & CO. (OLDBURY) Ltd. May 8, 1964 [May 9, 1963], No. 18475/63. Heading G3R. [Also in Division F4] A steam boiler is operated, when the output is below the modulating range of its firing means, by periodically firing and storing the firing energy by increase of water level and during the interval supplying a load through reduction in steam pressure and in water level. Below a low value of steam pressure in the boiler a pressure switch is closed to open a flue damper and light up an oil burner. As the steam pressure rises the low-pressure switch is opened and through relays a feedwater valve is opened and the water level raised to, and maintained between, limiting values of a low-water level by a float switch. Further rise in steam pressure actuates an intermediate-pressure switch to select a high-level float switch by which the water level is controlled. With further increase in steam pressure a pressure switch is operated to cause the damper to close and the oil burner to go out.

Abstract: 948,149. Contact members for switches; electromagnetic relays. SANGAMO WESTON Ltd. May 25, 1960 [June 8, 1959], No. 18514/60. Heading H2B. An instrument type relay has a sharp-edged moving contact arranged to engage a fixed wire contact and to move over the surface thereof with scraping action during further contact movement. As shown, the moving contact 12 has a sharp edge 12a which first engages a limb 18b of a wire 18 secured to an arm 17 of a setting indicator 14. Further movement of the contact 12 is assisted by the action of a contact pressure reinforcing coil in series with contacts 12, 18b and mounted with the operating coil 10 and the edge 12a engages a resilient blade contact 21 which is also secured to the arm 17. As the wire 18 and blade 21 are stressed the edge 12a scraps both these members to ensure good contact. The moving contact 12 is made of a hard material such as rhodium, a rhodium alloy, the wire 18 is made of a soft noble metal such as gold, or a gold alloy and the blade 21 is made of platinum iridium.

Abstract: 894,586. Gear-finishing. REGIE NATIONALE DES USINES RENAULT. June 10, 1958 [July 11, 1957], No. 18552/58. Class 83 (3). Four shaving machines 2, 6, 8, 10 are supplies with workpieces, each consisting of four gears on a shaft, by conveyers 1, 5, 7, 9. Each conveyer can be unlocked and moved transversely to permit access to the machines. The workpieces are loaded and unloaded from the machines at different levels, each conveyer having its loading section lower than the unloading section. The work is picked up from a holder 26 by an arm 24 rocked by a fluidpressure and pinion. The work is deposited on arms 39 resiliently supported on a carriage 31 moved transversely by a fluidpressure device 34. A pinion 42 associated with a torque-spring meshes with one of the work gears to assist in meshing the gear with the cutter, the gear being held between a fixed, and a fluid-pressure-operated, centre. The finished workpiece is moved by arms 49 on to a slide-way 52 leading to a carrier 55 of the conveyer leading to the next machine. The arms 49 are raised to receive a workpieoe by a roller 61 on the carriage 31 engaging a lever 60 which is connected to the arms through a link 57. The arms 49 are lowered by the weight of a workpiece therein. The workpiece is momentarily checked by a stop arm 53 actuated by movement of the carriage 31. The conveyer carriers are linked together by cables and are advanced along rods 75 by a fluid-pressure ram engaging pawls on the underside of the carriers. The cutters in each machine make several traverses with in-feed between each traverse. Switches and safety-switches control all the operations of the machines, a timing device being provided to permit a feed movement to take place after a time sufficient for the longest shaving operation to be performed. As each finished gear is deposited on to a carrier, a marking device punches on it the number of the cutter which machined it.

IPC: H01S3/107
Filed: 1968-04-19
Abstract: 1,193,026. Lasers. TOKYO SHIBAURA ELECTRIC CO. Ltd. 19 April, 1968 [19 April, 1967 (3)]. No. 18652/68. Heading H1C. A single output frequency laser has two partially-transmitting reflectors 13, 14, Fig. 2, forming a first resonator in which the active medium 12, e.g. He-Ne or CO 2 , is located, and comprises at least one external reflector 15 forming with the partially-transmitting reflectors a second aligned resonator, the intensity of the emitted radiation being controlled or modulated by changing the effective optical length of the second resonator, either by movement of the external reflector or by altering the refractive index of a medium located in the second resonator. The external reflector 15 in the arrangement shown is movably mounted on a plate 17 by a piezo-electric element 20 so that the effective optical length may be controlled by an electric signal. Further adjustment of effective optical length, or the attitude of the reflector 15 which also determines the output intensity, is effected by screws 18 against which the plate is biased by a leaf spring 19. In a modification, Fig. 3, the position of movable reflector 15 is controlled by an electromagnetic transducer comprising a magnet 30 fixed to a plate 16, and a coil 31 located between the reflector and a spring 32. An alternative arrangement is described, Fig. 4 (not shown), in which the transducer comprises a plurality of magnetostrictive rods. Fig. 5 shows the use of a medium 50 having a variable refractive index such as KDP, KTN or meta-lithium niobate or meta-lithium tantalate, the medium being provided with control electrodes S1, S2 and located between reflectors 14 and 15. Two external reflectors 61, 62 are used in the arrangement shown in Fig. 7, reflector 61 being fixed while reflector 62 is mounted for relative movement on a piezo-electric cylinder 64. In a modification of Fig. 7, Fig. 8 (not shown), both reflectors have similar adjustable mountings. A further modification, Fig. 9 (not shown), has a variable refractive index medium filling the space between reflectors 61 and 62. The arrangements using three reflectors may be used for measuring the velocity of a moving body, Fig. 10, the external reflector 15 being mounted on the body 80. The change in distance between the fixed reflector 14 and moving reflector 15 produces a sinusoidal variation of output intensity through reflector 13 which is detected by a photodiode 81. The frequency of output variation is proportional to the speed of body 80, and this is converted into a reading on voltmeter 86 by a circuit comprising an amplifier 82, Schmitt circuit 83, monostable vibrator 84 and an integrator 85. Alternatively, the photo-detector output may be applied directly to a digital frequency meter, Fig. 11 (not shown). Reference has been directed by the Comptroller to Specification 1,015,154.
